Special libraries are information centers that focus on specific subjects, industries, or organizations. Unlike public or academic libraries, they cater to specialized audiences, providing tailored resources and services. Examples include law libraries, medical libraries, and corporate libraries, which support professionals in their respective fields. These libraries often house unique collections, such as rare documents, technical reports, and proprietary databases. They also offer specialized services like research assistance, information management, and training programs. By focusing on niche areas, special libraries play a crucial role in supporting knowledge and decision-making within their communities.
